Near Threatened (NT) , assessed in 21/07/2016
Weinmannia paitensis is an endemic shrub/small tree of the southern part of Grande Terre and of Aoupinié in New Caledonia. It is found in humid forest and shrubland at mid and high altitude. The main impact identified comes from invasive species. However, this species does not seem globally threatened thanks to its altitudinal habitat. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 60 and 3,045 km², Weinmannia paitensis is considered Near Threatened (NT) close to VU B1ab(iii)+2ab(iii) with a decline of habitat quality and a number of locations close to 10.
Geographical area
Weinmannia paitensis is spread in the southern part of Grande Terre and in the Aoupinié massif in New Caledonia.
Population
Population size is unknown. It is known from 9-10 subpopulations.
Habitat
It is found in humid forest (edges and undergrowth) and dense altitudinal shrubland at mid and high altitude (500-1,600 m asl) on ultramafic substrate. A subpopulation is known in the Aoupinié on volcano-sedimentary.substrate.
Threats
The main impact identified comes from invasive species (Rusa rusa deer (Rusa timorensis), feral pig). However, this species does not seem globally threatened thanks to its altitudinal habitat.
Conservation
Unprotected by legislation, this species is found in several protected areas : Mont Mou, Haute Yaté, Haute Pourina, Mont Humboldt, Haute Dumbéa, Massif du Kouakoué, Forêt de Saille, Vallée de la Thy, Aoupinié, Rivière bleue. As a single subpopulation is known from province Nord and as it is genetically distinct, it is recommended to protect this species legally in province Nord.
